Mini Display Port

The Mini DisplayPort (MDP) is a miniaturized version of the external display connecting port. There are many other display connecting ports like VGA port, DVI port and HDMI port. All these are used for connecting external displays (like Projector, LED/LCD TV) to your laptop, notebook, desktop and mobile devices.

The main differences between Mini Display Port and other Display connecting ports are:

Size : There are practical issues. With other display ports, you have to use thumbscrews to insert and secure a connection; whereas you just have to push a Mini Display Port connector into place as you would with a USB device. And, you can’t easily bend a MDP (Mini Display Port) connector’s pins, like you can do with that of a DVI/VGA connector.

Higher resolution: The use of a digital micro-packet signaling protocol enables the standard to support higher resolutions. Mini Display Port supports up to 2560×1600 pixels resolution Display.

Audio: Generally audio signal is not transmitted through MDP but it depends upon the manufacturers of laptop/notebook/ultrabook. Some devices support audio transmission over MDP, but in case of no audio transmission we can use standard sound card that is the available audio out jack (3.5mm audio jack) on laptop/notebook/ultrabook for sound.

Mini Display Port was first introduced by Apple but now it is being adopted by a number of PC makers, these ports are generally used in notebooks/ultrabooks. Following are the devices which have mini display port:

Now the question comes to compatibility, which means whether external devices have Mini DisplayPort or not. If yes, there will be no problem. But, in case the external device has other standard display connecting port (VGA port , DVI port and HDMI port), we will have to buy display adapters ( Mini DisplayPort to VGA, Mini DisplayPort to HDMI or Mini DisplayPort to DVI) as per the requirement.
